8채널 24비트 ADC 모듈 -ADS1256, 낮은 노이즈
(ADS1256 24 bit ADC Module)
개요
- 본 제품은 8채널 24비트 ADC 모듈 -ADS1256입니다.
- 8개의 채널을 ADC할 수 있으며, SPI인터페이스를 통해서 마이크로컨트롤러와 인터페이스 할 수 있습니다.
- LP2985 LDO를 이용하여 저주파를 필터링 하여 낮은 노이즈를 보여줍니다.
특징
-
1. Power input terminal, the upper end is ground and the lower end is +5V.2. LT3461 power chip, high ripple noise rejection ratio.3. Power indicator.4.LP2985, LDO can effectively filter out low frequency noise, produce a very pure +5V, provide analog power for ASD1256.5. ADR431BRZ, B series is a high precision reference. The reference chip produces a high precision 2.500000V reference6. Benchmark test holes.7. Analog input, AIN0-AIN7 has a total of eight input ports, which can be used as 8 independent single-ended inputs, or as 4 sets of differential inputs. AIN0 and AIN1 are a group. AIN2 and AIN3 AIN4 and AIN5 AIN6 and AIN7 .8. Analog ground input9. Input resistance and attenuation resistance. The attenuation resistor is not soldered by default.10. ADS1256 main control chip.11. AMS1117-3.3v, which provides digital voltage to the ADS1256.12.NSK brand crystal oscillator, 7.68MHZ13. Communication interface with MCU.
